Embodiment Construction

[0023] In order to more clearly describe the method for discovering network devices proposed by the present invention, the following examples will be given for specific description.

[0024] Please refer to FIG. 1 , which is a system architecture diagram of an embodiment of the network device discovery method of the present invention implemented in a wireless network system 10 . The wireless network system 10 includes: at least one network management device 11 (NMS), at least one access point 121-125 (AP_1-AP_5), and at least one terminal 131-136 (T1-T6 ). These network management devices 11, access points 121-125, and terminals 131-136 are connected to each other through a wireless network environment 14, such as but not limited to: a wireless local area network ( WLAN), Global System for Mobile Communication (GSM), Integrated Data Packet Radio Service System (General Packet Radio Service; GPRS), Code Division Multiple Access (CDMA), ultra-wideband wireless local area networ...

Abstract

The invention discloses a method for discovering network devices, in particular to a discovery procedure for processing the network devices in a data link layer (the data link layer is the layer 2 of the network seven-layer architecture). The method comprises the following steps: firstly, a discovery data packet is sent out by a network managing device, and the discovery data packet at least comprises a command which requires the network devices to feedback the physical addresses thereof; secondly, at least one network device receives the discovery data packet, and a corresponding feedback data packet which is generated according to the discovery data packet is sent out, wherein, the feedback data packet at least comprises the physical addresses of the network devices; thirdly, the network managing device receives the feedback data packet, and at least extracts out the physical addresses, and a device information table is renewed according to the physical addresses after an IP address which can be probably contained in the feedback data packet is omitted, thereby identifying the network devices.

Description

technical field [0001] The present invention relates to a method for discovering a network device, especially a discovery procedure performed by a network management device in a data link layer (Data LinkLayer; that is, Layer2) in a local area network system to discover A network device discovery method for other network devices in the system. Background technique [0002] Due to the increasing demand of modern people for the portability of electronic information equipment and real-time information transmission, the wireless communication function has become a necessary consideration for the public when purchasing electronic information equipment. [0003] Take the WLAN communication system as an example, through the combination of radio frequency technology and network technology, users no longer need to connect physical network cables, and can connect with other network devices and transmit information through the WLAN. Although the wireless local area network communicati...
